SECTIONALLY-SPACED HOLLOW-WALL CONSTRUCTION.

Specification of Letters Patent.

Application filed November 27, 1916. Serial No. 133,718.

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1

This invention relates to improvements in hollow walls of the type embodying parallel spaced Wall sections built up of suitably webbed manufactured building blocks.

lVhile such walls, in a large degree, provide for maximum strength and required thickness, they at the same time very materially reduce the cost "of construction, and also permit of the proper formation of air ducts or passages, in vertical series, throughout the entire wall, for desired reasons well understood in the art, and without actually weakening the wall structure itself.

As the blocks of these walls generally are more or less analogous in structure in that they consist broadly of a flat base or body portion provided withtsuitable lateral spacing webs, it may be stated at the outset that, in the instant case, I: make no claim to the specific formation of the blocks per se, the primary object and advantage of the present invention residing in the combined relation and arrangement of such blocks as associated in the production of a novel wall construction itself, resulting from the manner of so setting the particular type of blocks that each course of the blocks positively bonds all of the vertical joinders of the blocks of the next succeeding courses above and-below, both as to the end faces of the adjoining blocks of each wall section and also as to the abutting faces of the spacing webs of the opposed parallel wall sections.

It is immaterial to my present invention, whether or not these building blocks are faced with a veneer or finished imitation surface of stone, marble, or otherwise, as is sometimes done.

The novel essence of the invention will be more particularly and succinctly stated in the appended claims, but to more clearly understand the same, reference is had to the accompanying drawings, forming a part of this application, in which the single View shows, in perspective, a corner section of a wall built up in accordance with my present invention, withthe courses of one wall so terminating as to clearly show the -disposition of' the blocks of one course relatively to the next succeeding courses.

In carrying out the present invention,

Patented Mar. 25, 1919.

blocks of similar design are employed, in 7 that they all have a flat base or body portion and lateral spacing webs, but the base of the blocks 1 are provided with spacing webs 2, which are substantially deeper than the short or shallow webs at of the blocks 3.

In theillustration, both sets of blocks are of the double-lug or web type, and while this may be most desirable, from my present actual experience, still it will be obvious, from the disclosure, that I am not so limited in use. Also, it will be seen that, while the webs 2 are very materially longer than the webs 4, all of the webs 2 are of the same depth relatively to each other, and similarly the webs at are all of the same dimension relatively to themselves.

In building my novelly constructed wall, one course of blocks is laid with the base of the long webbed blocks'l formingthe ex-:

blocks of the respective wall sections being cemented together, as usual, the vertical cement'joints beingindicated at 5, while the end faces of the opposed long and short webs abut' each other as indicated at 6, the arrangement providing the air chambers 7.

As the end faces of the webs 2 and 4: are not cemented together, there is naturally provided a more or less restricted air space communication between the vertical air chambers 7, which obviously may be proportionately increased, if desired, by distancing the end faces of the webs slightly apart, without in anywise deviating from my invention.

As illustrated in the drawings, the lowest course is shown with the blocks laid in the aforesaid relation, that is with the blocks 1 form a part of the interior wall section, with the end faces of the webs abutting, as at 6, near the outer wall body section.

In this connection, I wish to emphasize the fact that I do not merely reverse blocks in the sense of turning the same style of block over in a reversed position, but the block elements are entirely shifted and transposed, like a bodily unit as it were, so that the style of blocks, that formed the bodies of the respective wall sections below, now become, in thecourse above, component elements of the opposite wall section.

By this novelly combined arrangement of the blocks, the spaces 6, between the end faces of the webs 2 and, 4c, of the course below, are spanned by the long'webs 2 of the blocks 1, in the course above, bonding the sections together from the inner body wall section.

So also, in the next succeeding, or third course shown, the positions of the respective types of blocks are completely shifted or transposed back again, the long webs 2 spanning the joinder spaces 6, from the opposite or outer body section of the wall, in the intermediate or second course just referred :to.

It will also be understood that the blocks of the respective wall sections are so laid, as shown, as to break joints with the courses of adjacent blocks.

In addition to this breaking of joints, it will thus be seen that, in every alternate row or course, there is a bonding from opposite sections of the wall, through the long webs 2, co-acting as bonding elements, spanning the spaces 6, in addition'to functioning as spacing webs.

With the foregoing complete disclosure, it may be briefly statedvthat by the employment of my invention a spaced wall structure is produced, the parallel sections of which are positively and thoroughly interthroughout the whole wall, more evenly dividin the strains and pressure thereon, and guarding against settling and bulging.

Ilay no claim to any vgloroad manner of bonding other than encompassed by the scope of my invention as set forth in the ensuing claim, but what I do claim as patentably novel, is

In hollow wall construction composed of spaced sections, the employment of two sets of building blocks, each comprising a fiat base and lateral webs disposed at right angles to and of the same vertical depth as their bases, the webs of one set of blocks being substantially longer than the webs of the other setsbut of the same lateral length relative to their respective bases, and the bases of the long, webbed blocks forming a component part 0f one wall section while the bases .of'the short webbed blocks, in the same course, similarly function in the other wall section, with the end faces of the long and short webs disposed in opposed abuttingrelation, the arrangementof the blocks being so bodily transposed, in successive courses, that the bases of the respective sets of blocksare reversely located, in alternate courses, with-the longer webs of an intermediate course functloning as set' forth to overlap and bond, from opposite wall sections, the opposed long and short webs ofthe courses immediately above and below, substantially as described.

In testimony whereof,;I aflix my signature. JOHN A. FERGUSON.
